I have two problems using Compiz. One is that fixed window placement does not work: I want to bind for example my Guayadeque to the second viewport, so I added a rule to that effect under fixed window placement - windows with fixed viewport in Compiz' Place Window plugin (class=Guayadeque, viewport x=2, y=1). I tried every other type of window identification style, too, but it just opens in whichever viewport I am on at the time anyway. I tested it with Thunderbird and file browser windows, too. Same result.

The second is that the viewport switcher for the bottom panel does not work properly. I have set both vertical and horizontal desktop size to 2, number of desktops to 1 in Compiz-configs general settings, which should mean 4 viewports in a square, right?

The panel switcher, however, only displays one viewport after I log into the system. If I open the panel workspace switcher's preferences (set to 1 row, 1 workspace, otherwise each workspace shown in the panel is its own desktop with 4 workspaces), fiddle around with the settings, and put them back to 1/1, it goes back to displaying properly.

I activated Compiz by changing "marco" to "compiz" in mateconf's desktop/mate/session/reqeduired_components windowmanager key, replacing the command in Compiz' Window Deorations plugin with "/usr/bin/gtk-window-decorator" and copying the Mint-X theme folder to the Adwaita theme folder.Could this method of activation be part of the problem?

Forgive the double post, but I just notced another weird thing Compiz is doing: In its viewport switcher settings, I have set commands in the "go to specific viewport" tab for the first 4 viewports, because they are the only ones I use. The commands are <super>1 through 4. Any window I put next to the right edge on viewport 2 will now appear next to the left edge of viewport 1, whenever I <super>1 back to it, regardless of whether I went to a different viewport in between or not. No other edge does this.
